Can I add rapeseed oil after painting the gasoline tank?

The oil tank can be filled with rapeseed oil.

Oil drums are generally food-grade and can hold oil for a long time. Of course, it is best to use the same oil for used oil drums, such as vegetable oil or vegetable oil, olive oil or olive oil, so that there will be no odor. If you want to load different oil, you must clean the empty oil drum before loading it, so that the used oil drum can continue to be loaded with oil.
